I'm so sorry that this is going on. You must be a strong person to have survived all that you have so far. Doggonecarl is right though, it's time to go through a medical detox. At this point, who cares what anyone thinks...your LIFE is at stake! Believe me, the fact that you've been hiding this monster won't matter one bit when you're DEAD!
You've been sober for some long stretches before, so you must know what a different life living without alcohol is. Have you thought about what it is that makes you return to drinking? Unfortunately, I think your decision has been made for you though. You must know in your heart that you either give up alcohol or give up completely. You've got some life changing medical knowledge about yourself now, and a condition that dictates a sober life, or no life.
Of course people are reading your story! That's what people do here. And they care, too! I hope that you will choose to surrender and walk away from alcoholism. Please keep writing!
